WARMING A ND VENTILATING AND APPARATUS THEREFOR.

SPECIFICATION forming part of Letters Patent No. 283,149, dated August 14, 1883.

Application filed jNovemherfi, 1882. (NomodeL) Patented in England December 7, E81, No. 5,1il, and in Canada December 1, 1882, No. 15,876.

To all whom it may concern Be it known that 1, THOMAS RowllN, a sub: jectof the Queen of Great Britain, residing at London, England, have invented certain new and useful Improvements in Warming and Ventilating and Apparatus Therefor, the improvements being partly applicable to other purposes, (for which I have obtained a patent fin England, No. 5,351, bearing date the 7th 10 day of December, 1881 andsealed June 2,

a 1882,) of which the followin specification. This invention relates to iinprovedmeans or apparatus for introducing fresh warmed air a into buildings and the like, and treating such air so as to render'itpnoist for certain purposes-such as for use in millsand treating air so as to adaptit for medicinal or for curative purposes for use in hospitals, sick rooms, and the like. I provide a lamp, suitably placed. One or more tubes or passages (by i preference curved) passes or pass through the lamp-case, one end of such tubes or passages being open to the air, permitting the air to enter or be drawn or. forced through the here. 'inbefore-described tubes or passages, andas such tubes or passages are heated enternally by the said lamp, theair as itpassesthrough them is warmed, and then, before entering the building or room, it passes through a filtering-box of suitable construction, wherethe air is freed from dust, and, if required, from injurious gases or vapors also. The filtering box may be dispensed with. The lampispro vided with a casing and with a funnel for the discharge of the products of combustion, and may be heatedby gasor oil. The saidfunnel may also serve to discharge the vitiated air from the interior of the room by means of suitable openings. To establish the required current, the inlet from the atmosphere is at a lower level than the outlet by which the air enters the filtering-box. This filtering box or chamber is provided on the bottom, with a tray for holding water or other liquid, coke or other porous material being placed in the chamber inand abovethe water. The air thus becomes moistened and filtered before entering the chamber. In the case of spinning-mills as shown at i.

that thewater shall be heated as required. Further, in the case of hospitals for consump'- tives or those suffering from bronchial affections, I provide the filtering-chamber with a tray forcontaining pine-oil or eucalyptus-oil, which has properties like those of pine-oil, over which the air is made to pass before entering the chamber, and, if required, the air before entering the chamber may also be caused to pass through or over coke saturated or treated with the above-mentioned oil or oils. 6o Pine-oil, or coke, or other suitable porous material saturated with pine-oil, may be used without the aid of heat for curative purposes and by means of other forms of apparatus.

In order to enable my invention to be better understood and-readily carried into effect, I will now'proceed to describe the same by reference to the accompanying drawings, in which l V Figure 1 is a vertical section, showing my improvements applied to a building; and Fig. 2 is a vertical section of a modification of the arrangement shown in Fig. 1; Fig. 3, a trumpet mouth or cap. Similar letters in 'all the figures represent similar or corresponding parts.

V In the arrangement shown in Fig.1 the exterior air enters by inlet 9 and passes into the chamber (1,; andthrough the tubes 0, chamber 0, and tubes 0, and will be heated in its pas: sage by means of the heat from the burners b I) b, circulating round the tube 0 c, as shown by the arrows. The heated air from the tubesc passes into the filtering box or chamber 1., and is deflected by the plate 7, covered with fabric 1', onto the water m or other liquid contained in a trayin the bottom of thechamb'er Coke or other porous material is placed in the chamber above the water and on a perforated tray, n is a trough in the chamber i, the said trough containing any suitable disinfecting-liquid, in which dipsthe fabric 0. The air thus becomes moistened, filtered, and disenfected before it passes through the open ings Z into the room. In the case of spinningmills arrangements should be provided for a heating the water on to increase the amountof moisture.

The modified arrangement shown'in Fig. 2 will be understood without further description, similar letters to those used in Fig. 1 being used to represent similar or corresponding parts in Fig. 2. This modification is, however, more specially adapted where a fire or furnace is employed for heating the air instead of gas or oil, although gas or oil may be employed. Further, in the case of hospitals for eonsumptives or those suffering from bronehial affeetions,vI place in filteringehambers, such as are hereinbefore referred to, or in air inlet pipes or chambers, through which ventilating currents of air are made to pass, trays or vessel's containing pine-oil or eucalyptusoil, over which the air is made to pass before entering the chamber; and, if required, the

air before entering the chamber may also be caused to pass threugh or over coke saturated or treated with pine-oil or essential oil, as aforesaid, for the purposes stated.

Pine-oil, or coke or other suitable porous material saturated with pine-oil or eucalyptusto provide air, the conditions of which correspond with the air of those climates which have been proved to be beneficial to persons invention and the manner of performing the same, I. wish it to be understood that I do not claim, broadly, the mere heating of air by causing it to pass through aseries of tubes to which heat is applied for warming and ventilating purposes; but

WVhat I do claim is- In combination with case a and with its heating-burners, inlet-pipe g, and heating tube or tubes passing through such case, the water or filtering box i, deflector q 9', tray 2', trough 1L, fabric 0, and outlet-passages k and Z, substantially as and for the purposes set forth.

THOMAS ROWAN.
